一、概述 DSZ-100型振动三轴剪力仪,是吸取中国科学院工程力学研究所的经验,与北京市科学仪器修配厂等单位共同试制成功的。这台仪器,可以测定土试样在轴向等辐周期性循环荷载作用下的应力、应变及孔隙水压力的变化,从而得出土的动弹性模量,动强度、振动阻尼和振动变形等参数,并可 I. Overview The DSZ-100 vibration triaxial shear instrument is based on the experience of the Institute of Engineering Mechanics, Chinese Academy of Sciences, and was jointly developed with the Beijing Scientific Instrument Repair Factory. This instrument can measure the variation of stress, strain and pore water pressure of soil samples under axial and radial constant cyclic loading, and thus obtain the parameters of dynamic elastic modulus, dynamic strength, vibration damping and vibration deformation of soil.
